I started watching this show after reading the exact reviews here, but if you are like me they are misleading.
Don't get me wrong, the concept is unique and cool and we can still do with the average cast but there are too many plot holes that come up too often to ignore. The writing is sometimes unintelligent and although there are some twists the overall progress is very plot convenient. Also, it hugely disappoints when it comes scientific accuracy.
On a positive note, a few actors do shine and it's so out there in nature, overgrown and untouched by humans for about a century. And it has some cool shots of their space station(ark).
I will say it is watchable until you get tired of its many repetitive flaws.
